Designing Mediated Combat Play

ABSTRACT Supporting physical exertion is a growing trend in digital technology design. However, most experiences focus on bodily actions in which participants act independently of each other. In contrast, we focus on virtual body-to-body interactions between multiple participants, inspired by combat-oriented sports such as boxing that highlight the need to act while avoiding reciprocal bodily action. Mediating such body-to-body interactions with technology is challenging, particularly when participants are not colocated. Prior systems have often involved a mixture of novel physical interfaces and interactions through virtual avatars. This paper charts a design space for virtual combat play experiences and offers a set of design dimensions and recommendations for future systems. We draw on our experiences of designing and evaluating Remote Impact -a boxing-style exertion game involving aggressive bodily interaction with a large force-sensing projection surface. By expanding our knowledge of mediated exertion with an understanding of combat interactions we extend the social experience space of exertion play

Making metaethics work for AI: realism and anti-realism

Engineering an artificial intelligence to play an advisory role in morally charged decision making will inevitably introduce meta-ethical positions into the design. Some of these positions, by informing the design and operation of the AI, will introduce risks. This paper offers an analysis of these potential risks along the realism/anti-realism dimension in metaethics and reveals that realism poses greater risks, but, on the other hand, anti-realism undermines the motivation for engineering a moral AI in the first place

Papers, Please and the systemic approach to engaging ethical expertise in videogames

Papers, Please, by Lucas Pope (2013), explores the story of a customs inspector in the fictional political regime of Arstotzka. In this paper we explore the stories, systems and moral themes of Papers, Please in order to illustrate the systemic approach to designing videogames for moral engagement. Next, drawing on the Four Component model of ethical expertise from moral psychology, we contrast this systemic approach with the more common scripted approach. We conclude by demonstrating the different strengths and weaknesses that these two approaches have when it comes to designing videogames that engage the different aspects of a player’s moral expertise

Self-monitoring Practices, Attitudes, and Needs of Individuals with Bipolar Disorder: Implications for the Design of Technologies to Manage Mental Health

Objective To understand self-monitoring strategies used independently of clinical treatment by individuals with bipolar disorder (BD), in order to recommend technology design principles to support mental health management. Materials and Methods Participants with BD (N = 552) were recruited through the Depression and Bipolar Support Alliance, the International Bipolar Foundation, and WeSearchTogether.org to complete a survey of closed- and open-ended questions. In this study, we focus on descriptive results and qualitative analyses. Results Individuals reported primarily self-monitoring items related to their bipolar disorder (mood, sleep, finances, exercise, and social interactions), with an increasing trend towards the use of digital tracking methods observed. Most participants reported having positive experiences with technology-based tracking because it enables self-reflection and agency regarding health management and also enhances lines of communication with treatment teams. Reported challenges stem from poor usability or difficulty interpreting self-tracked data. Discussion Two major implications for technology-based self-monitoring emerged from our results. First, technologies can be designed to be more condition-oriented, intuitive, and proactive. Second, more automated forms of digital symptom tracking and intervention are desired, and our results suggest the feasibility of detecting and predicting emotional states from patterns of technology usage. However, we also uncovered tension points, namely that technology designed to support mental health can also be a disruptor. Conclusion This study provides increased understanding of self-monitoring practices, attitudes, and needs of individuals with bipolar disorder. This knowledge bears implications for clinical researchers and practitioners seeking insight into how individuals independently self-manage their condition as well as for researchers designing monitoring technologies to support mental health management

The parasitic worm-derived immunomodulator, ES-62 and its drug-like small molecule analogues exhibit therapeutic potential in a model of chronic asthma

Chronic asthma is associated with persistent lung inflammation and long-term remodelling of the airways that have proved refractory to conventional treatments such as steroids, despite their efficacy in controlling acute airway contraction and bronchial inflammation. As its recent dramatic increase in industrialised countries has not been mirrored in developing regions, it has been suggested that helminth infection may protect humans against developing asthma. Consistent with this, ES-62, an immunomodulator secreted by the parasitic worm Acanthocheilonema viteae, can prevent pathology associated with chronic asthma (cellular infiltration of the lungs, particularly neutrophils and mast cells, mucus hyper-production and airway thickening) in an experimental mouse model. Importantly, ES-62 can act even after airway remodelling has been established, arresting pathogenesis and ameliorating the inflammatory flares resulting from repeated exposure to allergen that are a debilitating feature of severe chronic asthma. Moreover, two chemical analogues of ES-62, 11a and 12b mimic its therapeutic actions in restoring levels of regulatory B cells and suppressing neutrophil and mast cell responses. These studies therefore provide a platform for developing ES-62-based drugs, with compounds 11a and 12b representing the first step in the development of a novel class of drugs to combat the hitherto intractable disorder of chronic asthma
